Straighter path

A project log for Hybrid Extruder for the Prusa i3 MK2 MultiMaterial

My ongoing effort to print NinjaFlex with support material on the Pursa i3 MK2 MM

In order to simplify the extruder path, today I used a different piece of PTFE tubing to run the filament straight from the extruder into the hotend (replacing the usual hotend PTFE liner). This gave me a much more direct path from extruder to heat block. The result (no photos - sorry) was much improved with the NinjaFlex being extruded far more reliably. Not *quite* print quality yet, but a little fussing with temperatures and extruder speed might be enough to fix that. This gives me hope that, if I can straighten the pathway for the flexible material, this still might work.
